TORONTO -- The Senators could be forced to make another lineup change tonight because of an injury to defenceman Filip Kuba.

Coach Cory Clouston said this morning Kuba may be sidelined with a lower body injury against the Toronto Maple Leafs at the Air Canada Centre. If he is unable to suit up then Alex Picard will dress for the game (7 p.m., TSN, Team 1200 radio).

"Kuba will be a game-time decision," said Clouston.

Not that a Battle of Ontario game needs another story line, but tonight's match is getting a big one in the Toronto net. The Senators discovered at the game-day skate that they will get a first-hand look at The Monster. The Leafs have elected to give rookie goaltender Jonas Gustavsson his first NHL regular-season start tonight, ahead of Vesa Toskala.

The move is adding fuel to an already-raging goaltender controversy in Toronto. The discussion was reignited after Toskala gave up three early goals in a 6-4 loss to the Washington Capitals on the weekend and was pulled.

"I have to be alert all the time and focused all the time," said Gustavsson.

Asked what he knows about the Senators, Gustavsson said: "I know they've got a good Swede in (Daniel) Alfredsson and a good Swede on defence (Erik Karlsson)."

The Toronto players were facing plenty of questions about Gustavsson.

"We're a team and we stick together. It's not about one guy," said Toronto defenceman Mike Komisarek.

Toronto coach Ron Wilson said Gustavsson deserves the chance to play.

"Vesa is just not in form right now, but I have confidence in Vesa," said Wilson.

The Senators other lineup change will see Ryan Shannon (head) out of the lineup and Shean Donovan making his first appearance.
